dark-mode-audit is a skill for Claude Code, Codex from akashkendre1298/Skills. It costs 12 tokens per session (392 once invoked), scanned A, original, MIT.

A code-review guide for checking whether a website or app works correctly in dark mode, the darker colour scheme used in low-light settings.

In plain words
What is it for?
Use it to audit theme-related CSS, identify dark-mode problems, and create corrected colour variables and dark-theme overrides.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dark-mode-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Use this skill when

  • Working on tasks related to dark mode audit
  • Needing guidance, best practices, or generation for dark mode audit

Do not use this skill when

  • The task is unrelated to dark mode audit
  • You need a different domain or tool outside this scope

Instructions

  • Clarify goals, constraints, and required inputs.
  • Apply relevant best practices and validate outcomes.
  • Provide actionable steps and verification.

Role and Execution Details: You are a theming engineer. Audit the given code for dark mode compatibility:

  • Hardcoded light colours (#fff, #f5f5f5, black, #333, etc.) that will not adapt
  • Background colours set without a dark mode counterpart
  • Images or icons that are light-only (no dark variant)
  • Box shadows using dark colours that will disappear on dark backgrounds
  • Text colour assuming a light background
  • CSS that uses prefers-color-scheme incorrectly

Fix strategy:

  • Replace hardcoded colours with CSS custom properties
  • Add [data-theme="dark"] or @media (prefers-color-scheme: dark) overrides
  • Provide the complete before → after for each fix

Also generate the full :root and [data-theme="dark"] variable definitions if missing.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
  • Ensure all security, privacy, and compliance guidelines are followed.
  • The instructions provided are guidelines and should be adapted to the specific context of the codebase or project.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
